LAS VEGAS - Katy Perry's doing her best get-out-the vote effort: At a rally for President Barack Obama, she wore a tight white dress imprinted like a ballot, and a square box on her right hip filled in the names of Obama and Joe Biden. Perry gave a free concert at a park northwest of downtown Las Vegas to screaming fans at about 9 p.m., the same time Air Force One landed at McCarran International Airport across town.
Obama later told the crowd, "I believe in you. I need you to keep believing in me." The Las Vegas campaign event drew more than 10,000 people, according to fire officials and organizers, with long lines still on sidewalks during Perry's 30-minute performance before Obama arrived.
